TIMER FOR AUTOMOBILES.

Specification of Letters Patent.

Patented Oct. 25, 1910.

Application filed February 25, 1910. Serial So. 545,968.

T all whom it may concern:

Be it known that I, \VILIJAM S. Jones, a citizen of the United States,residing at. Ossining, in the county of VVQStCl'lQSi'QI and State of NewYork, have invented new and usefulImprovements in Timersfor Automobiles,of which the following is a spec1ti-- cation.

The invention relates to an improvement in timers for automobiles, beingmore particularly directed to a-ti ming ring constructed to permit itsconvenient disconnection and adjustment to take up lost motion on thecam shaft.

The'main object. of the present invention is the provision of a timingring having its shaft-engaging bearing divided longitudi- 'nally withone section integral with the disk of the ring and the other sectioncarried on an arm fitting in an opening formed in the disk of the ringand projecting beyond the contact-carrying flange to provide for theconnection of the usual control rod the independent bearing section thusprovided being formed with means whereby they may be adjusted withrelation to each other to take up any undue lost motion of the timerwith relation to the cam shaft.

The invention in the preferred form of detail will be described in thefollowing specification, reference being had particu- 'l'arly to theaccompanying drawings, in

which 1- Figure 1 is a view in elevation of the im- 35 proved timer.Fig. 2 a perspective view of the main portion of the improved timer.Fig. 3 a perspective view of the remaining portion of the improvedtimer. Flg. 4 1s a view in elevation of,the improved timer taken fromthe side opposite that shown in Fig. 1. Fig. 5 is a vertical sectionalview through the improved timer, the contacting clement being omitted.

Referring particnlarlylo the accompanying drawings, the in'iproved timerincludes the usual contact element 1 fixed upon the cam or timer shaft2, and carrying a spring contact arm 3 having a roller 4-. The roller 4forms one terminal of the circuit, and the sparking points aresuccessively energized therefrol'n through the medium of contact riders5 which are secured in openings 6 formed in a contact-carrying flange ofwhat is known as a timer.

The present invention is directed particularly to improving the timingring, which bearing alines with an opening 11 formed in the head whichopening is continued throughout the-disk head beyond the half bearing toprovide an opening 12. The opening 12 extends through thecontactcarrying flange and in the flange has a dimension in line withthe thickness of the disk head which is somewhat greater than thethickness of the said head. In other Words there is formed in the flangean entrance to the opening 12 which has a dimension transverse theflange exceeding the thickness of the head. 7

Arranged for cooperation with the main section of the timer is an arm13, which arm, or more appropriately adjusting section has a thicknessand width corresponding with that of the opening 12, and is provided atits relatively inner end with a half bearing 14 and end lugs 15 tocooperate with the similar parts of the main section of the timer. Theouter end of the adjusting section is formed with a laterally projectingflange to fill the additional area of the entrance opening previouslynoted, and bcyond the end of the section and offset from the forwardface thereof is an car 16 formed with an opening 17 to provide for theconnection of the usual control rod.

The lugs 10 and 15 are formed with openings 1.8, those in the lugs 10being threaded, and adjusting screws 19 cooperate with said openingswhereby the respective half bearings may be relatively adjusted toaccurately accommodate the timer to the cam shaft.

The operation of the device in the particular detail of constructionenumerated will be readily apparent from the above description taken inconnection with the drawings, it being obvious that through the easewith which the adjusting section may be disconnected to permit readyseparation of the timer from the cam shaft, and the means C eluding amain section formed with a half bearing and with an opening extendingtrom the bearing, an ad usting section fitting in said opening andcarrying a half I bearing to cooperate with the half bearing of the mainsection, and a control rod engaging ear carried by the adjustingsection.

3. An automobile timer timing ring infrom the bearing, an adjustingsection fitting in said opening and carrying a half bearing to cooperatewith the half bearing of the main section and means for removahlyconnecting said main and adjusting sections.

In testimony whereof I afiix my signature in presence of two witnesses.
